Notojima Aquarium — Underwater Tunnel & Dolphin Shows
Notojima Aquarium (のとじま水族館) is located on Notojima Island in Nanao Bay, showcasing the marine life of the Sea of Japan and Noto Peninsula's rich coastal ecosystems. The aquarium's highlight is a 22-meter underwater tunnel through a massive tank containing 20,000 fish including yellowtail, sea bream, stingrays, and sharks — visitors walk through as fish swim overhead and around them. The jellyfish exhibition features 20+ species displayed in illuminated tanks that highlight their translucent, otherworldly beauty.
The facility also includes dolphin and seal shows (4 daily performances), a touch pool where children can handle starfish and sea cucumbers, and a penguin enclosure where Antarctic penguins waddle across artificial snow. The aquarium emphasizes local marine life — exhibits explain traditional Noto fishing methods, display local shellfish and seaweed varieties, and feature the giant Echizen crab (live specimens in winter). The location on Notojima Island (connected to the mainland by bridge) combines the aquarium visit with scenic coastal driving and views of Nanao Bay's oyster rafts and fishing boats.
